Storage Symptom After Laser Prostatectomy

February 25, 2014 updated by: Seoul National University Hospital

Change in Storage Symptoms Following Laser Prostatectomy: Comparison Between Potassium-titanyl-phosphate Photoselective Vaporization of the Prostate (PVP) and Holmium Laser Enucleation of the Prostate (HoLEP)

Recent literature indicated that postoperative storage symptoms after Photoselective vaporization of the prostate (PVP) or holmium laser enucleation of the prostate (HoLEP) were often reported and generally more common than after transurethral prostatectomy (TURP). However, almost all literature focused on postoperative urgency or dysuria immediately after PVP or HoLEP. Thus, there has been a scarcity of data on serial changes of storage symptoms in the postoperative period after PVP or HoLEP and data on predicting factors that influence improvement in storage symptoms postoperatively. The aim of this study was to compare serial changes of postoperative storage symptoms between PVP and HoLEP, and to identify the predictors that influence improvement of storage symptoms postoperatively.
